Riesling in the context of "Barossa Valley (wine)"

White wine is a wine that is fermented without undergoing the process of maceration, which involves prolonged contact between the juice with the grape skins, seeds, and pulp. The colour can be straw-yellow, yellow-green, or yellow-gold. It is produced by the alcoholic fermentation of the non-coloured pulp of grapes, which may have a skin of any colour. White wine has existed for at least 4,000 years.

The wide variety of white wines comes from the large number of varieties, methods of winemaking, and ratios of residual sugar. White wine is mainly from "white" grapes, which are green or yellow in colour, such as the Chardonnay, Sauvignon blanc and Riesling. Some white wine is also made from grapes with coloured skin, provided that the obtained must is not stained. Pinot noir, for example, is commonly used to produce champagne.

The Moselle (/moʊˈzɛl/ moh-ZEL, French: [mɔzɛl] ; German: Mosel [ˈmoːzl̩] ; Luxembourgish: Musel [ˈmuzəl] ) is a river that rises in the Vosges mountains and flows through north-eastern France and Luxembourg to western Germany. It is a left bank tributary of the Rhine, which it joins at Koblenz. A small part of Belgium is in its basin as it includes the Sauer and the Our.

Its lower course "twists and turns its way between Trier and Koblenz along one of Germany's most beautiful river valleys." In this section the land to the north is the Eifel which stretches into Belgium; to the south lies the Hunsrück. The river flows through a region that was cultivated by the Romans. Today, its hillsides are covered by terraced vineyards where "some of the best Rieslings grow". Many castle ruins sit on the hilltops above wine villages and towns along the slopes. Traben-Trarbach with its art nouveau architecture and Bernkastel-Kues with its traditional market square are two of the many tourist attractions on the Moselle river.

Mosel (German: [ˈmoːzl̩] ) is one of 13 German wine regions (Weinbaugebiete) for quality wines (Qualitätswein, formerly QbA and Prädikatswein), and takes its name from the Mosel River (French: Moselle; Luxembourgish: Musel). Before 1 August 2007 the region was called Mosel-Saar-Ruwer, but changed to a name that was considered more consumer-friendly. The wine region is Germany's third largest in terms of production but some consider it the leading region in terms of international prestige.

The region covers the valleys of the rivers Mosel, Saar, and Ruwer from near the mouth of the Mosel at Koblenz and upstream to the vicinity of Trier in the federal state of Rhineland-Palatinate. The area is known for the steep slopes of the region's vineyards overlooking the river. At 65° degrees incline, the steepest recorded vineyard in the world is the Calmont vineyard located on the Mosel and belonging to the village of Bremm, and therefore referred to as Bremmer Calmont. The Mosel is mainly famous for its wines made from the Riesling grape, but Elbling and Müller-Thurgau also contribute to the production, among others.

The process of fermentation in winemaking turns grape juice into an alcoholic beverage. During fermentation, yeasts transform sugars present in the juice into ethanol and carbon dioxide (as a by-product). In winemaking, the temperature and speed of fermentation are important considerations as well as the levels of oxygen present in the must at the start of the fermentation. The risk of stuck fermentation and the development of several wine faults can also occur during this stage, which can last anywhere from 5 to 14 days for primary fermentation and potentially another 5 to 10 days for a secondary fermentation. Fermentation may be done in stainless steel tanks, which is common with many white wines like Riesling, in an open wooden vat, inside a wine barrel and inside the wine bottle itself as in the production of many sparkling wines.

The Clare Valley wine region is one of Australia's oldest wine regions, best known for Riesling wines. It lies in the Mid North of South Australia, approximately 142 km north of Adelaide. The valley runs north-south, with Horrocks Highway as the main thoroughfare.

The South Australian wine industry is responsible for more than half the production of all Australian wine. South Australia has a vast diversity in geography and climate which allows the state to be able to produce a range of grape varieties–from the cool climate Riesling variety in the Clare Valley wine region to the big, full bodied Shiraz wines of the Barossa Valley.

Some of Australia's best-known wines like Penfolds Grange, Jacob's Creek, Yalumba and Henschke Hill of Grace are produced there, as well as many of Australia's mass-produced box wines.

Old vine (French: vieilles vignes, German: alte Reben), a common description on wine labels, indicates that a wine is the product of grape vines that are notably old. There is a general belief that older vines, when properly handled, will give a better wine. There is no legal or generally agreed definition for old.
